yep...

that *would* cause slowndown... but back-up/restore is not needed to fix it.

In fact.. the fix is in the application (transaction control), and if
the application could not be fixed a simple SWEEP (gfix -sweep) would
fix that if run when no one is connected (I assume that it is possible
since he could back-up/restore)

see you !
